Title:
SEPARATION MEMBRANE CONTACTOR MODULE AND MEMBRANE CONTACT SYSTEM AND MEMBRANE CONTACT METHOD FOR PURIFYING BIO-GAS USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/143920
Kind Code:
A1
Abstract:
The present invention relates to a separation membrane contactor module and a membrane contact system and method for purifying bio-gas using the same, in which: the separation membrane contactor module having a flow path control tube (240, 540) installed therein is provided to activate a cross flow, thereby enhancing gas separation efficiency, the flow path control tube (240, 540) having a partition (243, 543) therein; an absorption separation-membrane contactor module (200) and a degassing separation-membrane contactor module (400) are connected to each other such that liquid continuously circulates through the shell sides of the respective modules that communicate with each other; the separation of gas is performed at the tube side of the absorption separation-membrane contactor module (200), and the reduction of pressure is performed at the tube side of the degassing separation-membrane contactor module (500); and a degassing tank (300) is provided on the liquid circulation line to allow degassing to be performed through a change in solubility according to a pressure change, thereby refining high-purity methane from bio-gas.
